VAPORIZER.

SPEGIFICATION forming part of Letters Patent No. 678,714, dated July 16,1901.

Application filed January 19, 1901. Serial No. 48,863. (No model.)

zen of Germany, residing at Munich, Germany, have invented certain newand useful Improvements in Vaporizers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it ap pertains tomake and use the same.

This invention relates to an apparatus for vaporizing medicated liquidsfor inhalingrooms and which may also be employed for regulating thetemperature and for replenishing the air.

In the accompanying drawings, Figure 1 is a vertical section, partly inelevation, of my improved vaporizer. Fig. 2 is a horizontal section online 2 2,- Fig. 1; Fig. 3, a detail sectional elevation of the nozzle b;Fig. 4, a plan thereof; and Fig. 5 isavertical section, partly inelevation, of a modification of the vaporizer.

The vaporizer is designed to operate by means of compressed air in sucha manner that a minute spraying of medicated liquids is obtained andthat the other above-enumerated objects sought to be accomplished areproperly effected.

The letter a represents a vessel adapted to receive the liquid to besprayed and containing centrally a spraying-nozzle b and a number ofblast-pipes c j, arranged at dilferent elevations concentrically tonozzle Z).

The spraying device consists of a stand-pipe d, which is connected bytube 6 with a tank or receptacle containing com pressed air. The upperend of stand-pipe d enters the centrally-perforated hollow disk-shapedrose or nozzle 2), the interior of which communicates with a number ofsuction-pipes f, that enter the fluid in vessel a. Upon admitting thecompressed air into tube 6 it will upon escaping through pipe cl suckthe liquid through pipesfand convert the same into a fine spray,escaping through nozzle (9-. Owing to the peculiar construction andarrangement of this nozzle such a very fine spraying effect is obtainedthat with but one atmospheric pressure liquid drops cannot be found by amicroscope even in the center of the jet. The verticallyarrangedblast-pipes are operated simultaneously with the atomizing-nozzle andare supplied with compressed air by a second feedpipe h. The jets ofcompressed air emitted by the pipes c g elfect a further subdivision ofthe inhaling liquid already sprayed by the nozzle 12. Thus as suchliquid enters the in haling-chamber it will be in the form of the finestatoms, which possesses the further advantage that the occupants of suchchamber will not become wet. The blast-pipes c 9 may also be utilizedfor supplying the chamber in abundance with fresh bodies of pure airrich in oxygen. This prevents an accumulation of carbonic-acid gas,which is naturally formed by the presence of a number of patients andwhich is very unpleasant and injurious.

Should a complete change of air be desired inthe inhaling-chamber, thiscan be readily effected. It is only necessary to close the feed-pipe eof nozzle b, to open the feed-pipe h of blast-pipes c g, and to open aWindow in the chamber, when a complete renovation of air will take placein a very short time. In an equallysimple manner the apparatus enablesthe temperature of the inhaling-chamher to be regulated. The air isnaturally heated by being compressed Within the compressed-air tank. Ifa cooling-worm is placed around the latter, through which cold water ismade to flow, the compressed air will be cooled and will enter theinhaling-room ina cooledstate. Ifacoolingofthe airisnolonger desired,the flow of cold water through the worm surrounding the compressed-airtank is stopped.

For sanitary reasons the air supplied to the apparatus should passthrough a filter of wadding on its way to the tank.

The apparatus is provided with an open frame e, projecting above thevessel ct and supporting a removable lid 2'.

The air-blasts emitted from the pipes c g are blown into the spray inthe same general direction as the flow of the spray. In this way thespray is vaporized or diffused over a greater area and its impetus isgreatly increased. It is obvious that the concentric arrangement of theblast-pipes is not a necessary condition for attaining this purpose. Itwould be sufficient to let the dry air escape into the inhalation-roomin a manner suitable foratomizing the spray. A simplified form of theinvention embodying this modification is illustrated in Fig. 5. Here thevessel a, containing the liquid and inclosing the nozzle b,is placed atany convenient place in the room. The compressed air is brought inthrough the blast-pipe g or through several blast-pipes g c, disposed ata suitable height above the atomizer. -Wl1en the latter is started anddry air escapes through the pipes g c, the atomizing effect will besimilar as with the concentric arrangement of the blast-pipesillustrated in Fig. 1.

I claim I r The herein-described vaporizer for rooms;

consisting of a chamber provided with a nozzle, means for feeding aliquid and compressed air to said nozzle to form a spray, andindependent blast-pipes within the chamber adapted to subject the sprayto the action of fresh bodies of expanding compressed air, as set forthand described.

In testimony whereof I affix my signature in presence of two witnesses.
